Rehab

I don't know if I've talked about this here before. My father is an alcoholic. He has been my entire life. So I always have mixed feelings when I hear about someone going into rehab for alcohol detox. On one hand, it has worked for a lot of people. On the other hand, I've watched my father fail time and time again in rehab. It feels like it's such a waste of time and money. I guess I should try to be more supportive and open minded to the whole experience. It has to do some good for someone, right?
